YES. Not Ideal, think 245 or 235 would be best. With 225 you will get a little stretch on the sidewall but not much. 225 is very doable.
no, the rim size is 2 inches different.
No. Sorry!
Yes, a 245/75R16 tire can fit an 8-inch wide rim. This tire width is compatible with rim widths between 6.0 and 8.5 inches, making an 8-inch rim suitable. However, always consult the tire manufacturer's specifications for the best fitment and performance.
Standard 35-12.5 tires will fit on a 15-8 rim but will hang over the sides a bit. This provides a secure seal around the bead and helps to keep them on the rim.
Simply, no. 8" tires are made to go on 8" rims
i wont recommend it, 225-50 or 60 are pretty much the safe limit on those rims size
the R stands for RIM , Example R15 Is a 15 Inch Rim The R actually means it is a tire of Radial construction. The wheel & tire diameter is 15" but the width of the rim should be 7" to 8" for this size tire.
it should fit but it will be kind of ballooned out since its 2 inches wider and as long as you have the clearance on whatever the wheel goes to you should be fine but both wheels are 8 inch diameter,maybe you get lucky and the rim is 7 or 7.5 wide but either way it should fit fine
yes
That depends entirely on the application.
YES it will
No
